I have been running a build of Cyanogen mod that I initially discovered at http://galaxytabhacks.com/galaxy-tab-10-1-roms/cm10-jelly-bean-rom-for-galaxy-tab-10-1-android-4-1-2/ when I initially received the tablet from my wife back ATC Christmas (and had upgraded from Honeycomb within just a few hours). Since I’ve got the next week off from work and I had really wanted to get a little better performance out of Google Now, I decided to finally give one of the nightlife a try this evening. I did my Nandroid backup and performed the update, then updated gapps t the latest version from goo.im. Still working some kinks out, and indeterminate at this point whether I will remain on this version (Google Now does appear to b working great) or restore the Nandroid.
My major complaint with the nightly is that the keyboard crashes every couple of seconds; that’s a Royal pain in the ass, as its surprising just how much text entry I do on my tablet. After more pissing around than I really like, I did finally locate a replacement keyboard that is fairly similar to the AOSP version (which I find comfortable for typing and pretty accurate at replacing words with what I intended to type) and that doesn’t crash. In case you find yourself in the same boat, check out Jelly Bean Keyboard. It’s not identical, but thus far I have found it comfortable. I’ll give it a couple of days and see how it grows on me.
In hindsight I probably would have just stuck with the 10/30 build from the post I originally linked, and I may yet revert. It was ridiculously stable and the battery life was absolutely unbelievable. Also still unable to update to the most current version of Google Search from the Play Store – crashes every time I attempt to launch it after installing the update until I roll back to the default version. Still, I will give it a couple of days before I firmly make up my mind.
